Children nationwide are trading in their televisions for phones and iPads, according to a study from Common Sense Media released today.

The study found that a whopping 72 percent of children eight and under have used tablets or smartphones (and more than a third of babies under two!). In 2011, only 38 percent of children used mobile devices or tablets, an initial survey from the family advocacy group found two years ago.

But the same age group is watching less television and movies and spending less time on the computer or playing video games. Kids spent on average of an hour and nine minutes a day watching television, which has dropped to 57 minutes in 2013.

“These kids are true digital natives,” James Steyer, CEO of Common Sense Media, said in a statement.
